I'm getting more and more annoyed by the speed of firefox. Mainly in Gdocs or wordpress admin editors.
So I turned off extensions to speed it up. After trying a few combination I discovered that firebug is the biggest source of slowdown. Being a web-developer I want to switch to the build in FF inspector.

question

Is there a way to make the ff inspector collapse both the HTML(dom tree) and the style editor when I inspect an element or press ctrl+shift+I?

Is there a way to keep it collapsed out on refresh (if I collapsed it before)?

I see, also shift+F12 does that. I'll keep it as an backup solution. But I'd prefer to quit firebug.

You might get more responses to your question if your question were more specific than "Firefox inspector." You list two questions in your description--why not make one of them your question instead of "firefox inspector"?
